preciable tonnage and passenger capacity with telephone service of theautomatic type.

with such systems, are in many instances, lo cated in such parts of avessel as to be subjected to splashes of ocean spray, rain and the like,it is necessary, in order to maintain. uninterrupted service ofasatisfactory nature, that some, means be provided for guard-- ing suchequipment from the efiects or these unavoidable conditions.

It is the object of this invention to incorporate in the structure of animpulse trans mitter means for splash-proofing the operating mechanismthereof.

This object is attained in accordance with a feature of the invention'bythe provision of a plurality of cooperating saucer-like ele- J mentsforming a part ofthe dial superstructure, which coact to prevent'theingress of water to the dial mechanism, g

The invention will-be readily understood from the following 5 detaileddescription made with reference to the accompanying ,7 drawings inwhich, Fig. 1 is a side elevation,

' partly in section, of a dial embodying the features of the inventionand Fig. 2 is a plan view ofthe dial shown in Fig. 1. The sectionalportion'of Fig. 1 is taken along the line 1-l of Fig. 2 looking in thedirection of the arrows.

Referenceis madeto, Figs. 1 and 2 jointly, and like numerals indicatesimilar parts throughout the drawings. I

A case or receptacle'5, which servesas ,a housing for the dial mechanism(not shown) is provided with a circularflange'G' which serves as asupport or shelf upon which discs or saucer-likeelements 7 and 8 aremounted, interposed between the annular number plate and acorrespondingly-shel ed llbbergasket on the" hub 12 screw 14.

r9291; Serialil l 'oa3 @3131, ,1 I I c 11.1 Inorder to clarify thatparticular part ofthe drawings, a screw 10 and its cooperatmg nut: areshown as one 'ofthree such sets which are employedto secure the elements7, 8, 9 and 11 to theflange 6 of the dial case 5. Amo're desirablemethod, however, would be to weld threaded I studs to the underside of,the number plate in place of the screws 10.

Each ofthe discs 7 and 8 is, provided with a centrallyflocated circularhole through which the hub 1210f the dial me hanism 6 tends. fingerwheel 13 fits overa shoulder s em c hfe sl ith Thezdiscs; or in eredsaiiberiiks elements 7 and S'are providedwith skirted ends whichcooperate .to form' areserv'oir 15; The hub 1121, is f provided .with a'ledgerlike flan e is which is so lo'catedi'on the hub as toextendsubstantially midway between the skirted ends ofdiscs Tend i f" At. onepart,ithe' lower f 'disc 8 is to. .form aiduct -1 7 serves "to conductthe 1 water ,that accumulates in. the reservoir .15,.thereirom;,te theoutside ofthe upper disc r aylo' j h 1 161 s It isjnow apparent'jtlatanywater that splashes the dial and tends to drip along the -huband'eventuallydrops jint'othejoperating mechanism within the ,case 5, Iwill strike the ledge like'flange'lfi'and then drip intO the reservoir15 whence it finds its way to the outside byyway of the duct 17 and hole18.

In this manner the operating mechanism is guarded against thedeteriorating effects of Water.

. The'number plate9 is shown as an annular'ring extending beyondthe'outer edge of the finger wheel 13. This is for the purpose ofimprovingthe visibility of the characters under poor. lightingconditions which v at times are present on board ship.

Whatfis claimed is:

. 1. In combination with an impulse transmitting mechanism, a numberplate having an opening there'through, a receptacle for housing saidmechanism and provided with a flange for mounting. said number plate anda watershieldinterposed between said recep-,

tacle flange and said number plate and coverin the opening in saidnumber plate for sp ash-proofing said mechanism.

2. In combination with an impulse transmitting mechanism, a numberplate, a receptacle for housing said mechanism and provided with aflange for mounting said number plate and a Water shield comprising twodiscs interposed between said receptacle flange and said number plateand having skirted ends to form a reservoir, said discs cooperating toform a duct to permit water accumulated in said reservoir to flowtherefrom.

3. In combination with an impulse transmitting mechanism having areceptacle housing said mechanism and a hub with which certain parts ofsaid mechanism function centrally located within said receptacle, meansfor splash-proofing said mechanism comprising a pair of invertedsaucer-shaped discs mounted on a flange of said receptacle and havingaligning holes through which said hub extends and cooperating to form areservoir, and a flange on said hub extending between said discs withinsaid reservoir.

4. In combination with an impulse transmitting mechanism having areceptacle housing said mechanism and a hub with which I certain partsof said mechanism function centrally located within said receptacle,means for splash-proofing said mechanism comprising a pair of invertedsaucer-shaped discs mounted on a flange of said receptacle and havingaligning holes through which said hub extends and cooperating to form areservoir, one of said'discs having a depression to form a duct and theother of said discs having an aperture serving as an outlet for saidduct, and a flange on said hub extending between said disc within saidreservoir.

In witness whereof, I hereunto subscribe my name this 27th day of March,1929. HAROLD W. GOFF.

In witness whereof, I hereunto subscribe my name this 27th day of March,1929.
